Amorfa Permeability Reducing Additive
Spray-Lock Concrete Protection (SCP) technology was developed in the late 1970s to solve concrete permeability issues in some of the harshest conditions possible. Decades later, the term Permeability Reducing Admixture (PRA) entered ACI 212 to address the long-standing benefits obtained from preventing moisture movement in concrete, something SCP has known to be true for over 40 years. Amorfa reduces permeability while enhancing the overall characteristics of the treated concrete; working inside the concrete matrix to disconnect the capillary structure and generate resistance to fluid movement either into or out of the concrete. The level of resistance to fluid penetration ranges from a general reduction or to the levels required by hydrostatic pressures and aggressive exposures (PRA per ACI 212).
Concrete Durability Concrete’s durability is its inherent ability to withstand deterioration. Many factors go into the durability of concrete. Some influences that affect concrete durability are water to cementitious ratio, aggregate packing, reinforcement and type, curing methods, type of environment the concrete will be placed, finishing practices. Concrete is a versatile construction component but due to its porous nature and bleedwater channel formation, contaminants can be introduced into the concrete. All concrete, especially reinforced concrete is susceptible to contaminant ingress. The corrosion potential of reinforcing steel is directly related to the chloride movement into the concrete, disrupting the protective layer around the reinforcement and leading to rusting. SCP products can help reduce the corrosion potential of concrete by reducing the pathways of water and contaminate ingress. The P3 product line consists of spray-applied products that use colloidal silica technology to provide a permanent increase in the durability and lifespan of Portland cement concrete.
